Dome with horn and reflector
File: Dome - Horn Reflector.axi
This example adds a ring shaped reflector close to the dome of example Dome Horn. The two bars above the diaphragm in the sketch with SPL-field at 10kHz belong to a single reflector. The shape of the reflector is an annular disk.
The reflector is also specified on page Baffle.
Baffle front 29mm 1mm 35mm 3mm 50mm 2mm Reflector 6mm 7mm 19mm -1mm 19mm 1mm 6mm 1mm 6mm -1mm
There can be as many Reflectors as you like. Each Reflector starts with a line with the keyword "Reflector". The specification of Reflectors is a bit more involved than those for the baffle or the pole, because these items form free floating islands. Important to note is that a Reflector should have thickness and should form a closed body. The lines, which define the reflector-body should be ordered either clock- or anti-clock-wise. In the above example we start with a ring of 6mm diameter at 7mm above the base of the dome. Then we span the bottom-disk to a diameter of 19mm and a relative height of -1mm to the previous ring. The outer mantle is generated by the next entry. The top-disk is created by shrinking the diameter to 6mm again. Finally, we return to the starting point.
The spectral analysis similar to the previous examples shows an increase of sound pressure at higher frequencies of approx 3dB relative to the horn-example and 6dB relative to the direct-radiating dome.
